Wow, really? Nobody? I ended up DL it anyways. Wasn't able to play on "ultra spec", I have a Late 2012 iMac 27" 3.4GHz 16GB RAM GTX 680MX. I had to select "high spec" and boded well so far. Not sure why this computer cannot handle the "ultra spec". Anyone have any luck? Great game by the way, well, at least when the kids aren't whining and fighting.

check the 680MX Benchmark thread in the iMac sub forum, I remember people there talking about it. Ubersampling should be off when you play in Ultra, that feature is supposedly too much for even high end desktop GPUs in SLI.

And btw, do you play in OSX or Windows? I'm completely new to iMac and had been away from PC gaming for many years, but Windows allows for a way better gaming performance, just make sure you use the 310.70 drivers for the GPU.

As for the game, I just finished Witcher 2 a couple of months on Xbox, loved the game as well : )

Barely anything can handle 'ultra' when it comes to that game. It's one of the most demanding games around when run at full details.

Just got it today from Steam (75% off, yay) and it runs... well surprisingly unwell. I think some updated drivers or optimizations for the new GPU might be required before it can run as "it should" (if we're talking numbers and comparisons to other cards). It runs well on low/medium though.
